abdominal segment 2 in line with or but slightly anterior to seta 3 (contra Crumb's key).Larva in Last Instar.-Head about 3.5 mm. in width. Body 30 t o 35 mnl. long and 5 or 6 mm. broad. Skin smooth. General colour brown.Middorsal line narrow, pale, nearly continuous, distinct, and continuing onto thoracic and anal shields. Dorsum except for middorsal line with a pale ground colour overlaid by a dark-brown reticulation which is somewhat darker and less distinct near middorsal line and along ventral margin. Ventrum, including spiracular area, pale, of ground colour. Spiracles black-rimmed with yellowish centres. Setigerous tubercles I and I1 small, I11 moderate, all three dark brown; IV, V, and VI moderate, brownish; tubercules flat. Thoracic shield dark brown with pale middorsal and lateral lines. Head brown with a slightly darker reticulation; submedian arcs not always conspicuous.Comments.-Last-instar larva easily placed in couplet 15 of Crumb's key to species of the genus Apamea [Septis], but its colour description not applicable to that given for either species of that couplet, i.e., A. apamiformis or A.vultuosa. Hence, the material examined by Mr. Crumb (four inflated larvae collected in 1881 and 1882) was probably misidentified years ago.

A case of multiple endocrine neoplasia syndrome (MEN) in a 57-year-old woman with multiple endocrine tumours involving the pancreas, parathyroid and thyroid glands is reported. An unusual feature was the presence of collision tumours in the pituitary and adrenal. In the pituitary there were adenomas and a meningioma whereas in the adrenal there was a carcinoma along with a myelolipoma. Such collision tumours in the pituitary and adrenal as components of MEN syndrome have not been previously described.

The western spruce budworm, Choiistoneura occidentalis Freeman, which normally passes through an obligate diapause in nature, was reared in the laboratory without diapause. The critical factor for preventing diapause appeared to be the physical environment presented to the first stage larvae. The response of C. occidentalis was flexible. The 2nd stage larvae could be made to diapause or forego diapause, depending on their rearing experience in the first stage. By eliminating diapause it was possible to rear about 7½ generations per year as against about 2¼ under normal diapause conditions. The diapause of the jack-pine budworm, C. pinus pinus Freeman, and C. lambertiana californica Powell, could be prevented by the same technique. The diapause of the spruce budworm, C. fumiferana (Clemens), could not be eliminated except after several generations of selection.
